... Introduction Potassium is a crucial element in the body that is responsible for both cellular and electrical function. The blood serum contains between 3.5 and 5 mg of potassium in every 100 ml. The body potassium is derived from dietary sources, with the element well absorbed from the intestines. Excess potassium in the body is eliminated through urine while others are still eliminated via sweating. Adrenal hormone is responsible for the stimulation actions for elimination of potassium from the body; however, coffee, sugar, alcohol and diuretics can contribute to low levels of potassium (Alderman et al., 2012).

... Sodium Potassium Pump Sodium-potassium pump, also known as sodium-potassium adenosine triphosphatase, Na+ /K+ -ATPaseor Na+/K+ pump is a type of enzyme known as antiporter-like enzyme situated in the plasma membrane of the cells of every animal (Mary 23). Located strategically on the plasma membrane of a cell and just as the name of the enzyme suggests sodium potassium pump thrusts potassium into the cells of the animals while pumping out sodium out of the cells. While the enzymes perform the antiporter like function, they are not actual antiporter since the molecules it pumps in both directions flow against their gradient of concentration. In doing this, the enzyme performs fundamental functions...

... Sodium and potassium are cations that are found in the extracellular fluids such as blood plasma and intracellular fluids respectively and play an important role particularly in the brain, heart, muscle, heart and nervous system. They are involved in several body processes. For instance, sodium maintains normal body fluid levels in the body and blood pressure while potassium plays a vital function to the heart and in contraction of the skeletal and smooth muscle for the muscular and digestive function. In healthy individuals, the body is able to maintain fairly constant levels of sodium and potassium by balancing intestinal absorption with urinary excretion. However, severe malfunction of the heart ...

... Electrolytes disorders, hyperkalemia, hypercalcemia, and hypernatremia, and how they affect ourbody system: Introduction: Body fluids mostly comprise of water and electrolytes. Depending on the location of these fluids in the body they can be classified as either intracellular (ICF) or extracellular fluids (ECF). Composition of intracellular fluid remains relatively stable as compared to the extracellular fluid. This is due to the fact that ECF has to interface with the changes in the external environment therefore modifications in its constituents are inevitable. But any changes in the ECF can have an indirect impact on the composition of intracellular fluid. Electrolyte can be defined as...

... Potassium regulation of the heart and cardiovascular system. The cardiovascular system of the human body consists of the heart, blood vessels e.g. arteries, veins, arterioles, capillaries, and blood which flows in these vessels. The human heart is located in the middle of the thoracic cavity and is oriented in a diagonal plane such that its apex leans slightly towards the left side. It is covered in a fibrous sac known as the pericardium, except in areas where the great vessels attach to it. Within the pericardium is a small quantity of fluid which lubricates the heart surface and decreases friction between the pericardium and heart during contraction and relaxation. The heart has a pivotal function ...

... Vasodilatation in Vascular Smooth Muscles Vascular smooth muscles, or muscles which made up most of the blood vessels, are lined by vascular endothelia. The vascular endothelium is a single layer of squamous cells which come in direct contact with blood. Aside from the function of serving as containment of blood, the endothelium secretes and produces vasoactive substances that cause blood vessels either to contract (vasoconstriction) or dilate (vasodilation or vasodilatation). These substances include: the prostacyclin, a muscle relaxant and inhibitor of platelet aggregation; the endothelin, a vasoconstrictor, and; EDRF or the endothelium-derived relaxing factor. The EDRF enables the relaxation of...

... Nellie, Thanks for your letter. Yes, it was wise of Gladys to make you throw the fish in the compost heap. That fish would definitely have eaten a lot of mercury in that river! Heavy metals like mercury affect our nervous systems and cause terrible diseases like Multiple Sclerosis. Let me explain how.
Suppose you prick your finger when you are trying to hook the bait. You immediately drop the bait and withdraw your hand, before you have even thought about it. Your nervous system sensed the prick, and signaled your muscles to go back. It is your nervous system, which consists of your brain, spinal chord and nerves, that makes you feel, have sensations, think, play and act.
How do the nerves in ...

... School: RENAL COMPONENT ASSESSMENT IN ITU Lecturer: RENAL COMPONENT ASSESSMENT IN ITU Introduction One of the most crucial processes that should make up normal life for every other healthy person is the periodic filtering of waste products from the blood. This is a very important system function due to the fact that we continue to consume food products, which produce a lot of filtrate waste after the necessary transfusion into the blood stream of needed nutrients (John, Webb & Young, 2004, p. 827). As part of the anatomy of the human being, the kidneys are expected to perform this all important function described above. This notwithstanding, some people develop a medical condition where the kidneys...
